Frequently Asked Questions
Does WebP preserve transparency?
Yes. Any alpha transparency in your AVIF file is preserved in the WebP output.
Will I lose image quality?
WebP can use lossy compression, so some quality loss is expected at lower settings. At 92% quality or higher, the difference from the source is usually barely noticeable.
Is my image uploaded to a server?
No. The entire conversion happens locally in your browser using the Canvas API. Your image never leaves your device.
Is WebP widely supported?
Yes. All modern browsers support displaying WebP images, and most image editors and operating systems can open them as well.
Can I convert multiple files at once?
This tool converts one file at a time. For batch conversion, you'd need to repeat the process for each file.
